I have a problem with "link_to"

hello, everyone. I'm studying rails with version 2.3.5, but I got a problem just now. I wrote code like:

  <td><%= link_to 'Delete', :action => 'remove_from_cart', :id => cart_item %></td>

and I write that method like this. def remove_from_cart     @cart = find_cart     remove_item = params[:id]     redirect_to_index end unfortunately i found that remove_item isn't my CardItem class but a String. how could this happen? and how could i get cart_item in my remove_from_cart method by rewritng my code?

Of course it's a String - that's what "query*string*" parameters are :slight_smile:

- remove_item = params[:id] + remove_item = CardItem.find(params[:id])

HTH,
